KETOSIS
or
PREGNANCY TOXEMIA |
[Note: In
this article the term "Pregnancy Toxemia"
(or simply "Toxemia") and the word "Ketosis"
are used interchangeably.] |
In the spring
of 2005 we were anxiously awaiting the birth of NK
M141 Kattie's babies. We had purchased Kattie, and
she almost immediately gave us Samantha and Thunderbolt.
In March 2004 we used Kattie as the donor doe for
our flush. These 2005 babies would be her first after
the flush and hernia repair. |
All was going
well; Kattie (already a large doe) was getting bigger
and bigger by the day. About 15 days before her due
date, we noticed she was laying around all the time.
We figured as heavy as she was with the pregnancy,
walking just wasn't comfortable. |
Knowing Ketosis
(excessive ketone levels in the blood - a medical
condition caused by abnormally high levels of ketone
bodies in the blood resulting from the metabolism
of fats instead of carbohydrates for energy) was a
possibility, we started dosing her with Magic. |
10 days before
her due date, Kattie (and her 4 kids) died. The two
boys and two girls weighed a total of 28 pounds. |
Hindsight
is perfect. |
After her
death we realized that when Kattie started laying
around and not walking, she also quit going to the
water. We also realized we had not started treating
her soon enough – or aggressively enough. |
The day Kattie
died another doe who was due in 10 days delivered
a healthy 9 pound little girl. We should have induced
labor – but we had always read where kids born
more than 5 days early were considered premies and
the survival chance was slim. |
Fast forward
to 2006. |
We purchased
Melissa at a production sale in July 2005. In September
2005 we bred her to a friend's buck (who was purchased
at the same sale). This combination just had to produce
some fabulous kids!! |
Melissa, who
would turn 2 on 9 February 2006 and who had never
kidded, was a large-framed doe. Her due date was 13
February. So on 22 January, approximately 3 weeks
before her due date, we gave her the pre-kidding shots
of BoSe (because we are in a selenium deficient area),
Covexin 8, Super Poly Bac B Somnus (to protect against
pneumonia), and Vitamin A,D,E. On the same date we
trimmed her hooves – but not very close. |
After Melissa
returned to the barn, we noticed she was lifting her
front feet as though they hurt. We were sure we hadn't
trimmed too closely. The next couple days Melissa
always looked like her feet pained her. We didn't
notice if she was eating as usual; Melissa was in
such good shape we weren't really concerned about
her. But by Wednesday she appeared to be walking on
egg shells. Something more needed to be done. |
We took her
temperature; it was normal. We started bringing her
into the feed room so she could eat whatever she wanted
uninterrupted (well, as uninterrupted as one can be
with 5 little kids bouncing off the walls of the feed
room). We checked her feet again to make sure we hadn't
missed something. And that was when we noticed how
swollen her legs were. |
Ketosis! It
appeared that aggressive treatment was necessary.
We immediately started giving her Magic! |
We contacted
a friend (Coni Ross) who suggested we give her Calcium
Gluconate just in case she had hypocalcaemia and needed
a calcium boost. Our friend also suggested we give
her a scoop of corn to increase her sugar level and
give her energy. We were also reminded to give her
Calf Pac (a probiotic) to keep her rumen functioning
properly. And we were instructed to feed her all the
alfalfa hay we could get her to eat. |
Unlike Kattie,
Melissa continued to go out to the hay field with
the rest of the herd every day. Since she appeared
to be in a slightly weakened state, we decided to
keep her in the creeper at night where the other goats
couldn't beat her up (something the others wouldn't
consider doing if she felt good because she was among
the largest of our does). By being in the creeper
with everybody else locked out, she would be able
to eat all she wanted whenever she wanted, and she
could have corn which the rest of our herd is not
fed. We were able to put water in the creeper so she
could have plenty of fresh water to drink whenever
she needed it. |
By Sunday
we were getting more concerned. We had added Dextrose
and cranberry juice to our list of things to give
Melissa, as we noted she wasn't drinking much of her
water and she wasn't eating any of the feed/corn we
had out for her. And she was losing weight. Her temperature
was 103. |
When we noticed
the 2 inch string of fluid, we decided to call our
vet, Dr. Wyatt Galbraith, who said he would be right
out. We did not want her to go into labor so soon.
|
The first
thing he noticed about her was the rattle in her chest.
Pneumonia. He gave her an antihistamine shot along
with Banamine for pain. In addition, we gave her Nuflor
for the respiratory discomfort. He agreed with our
treatment with the Magic, Keto Gel, and Calcium Gel
– and also agreed she needed more in the way
of nutrients. He proceeded to tube her with ½
bottle of 50% Dextrose, ½ bottle of Pedialyte,
and about 8 oz. of water. He drew blood to check her
sugar level; it was 40; the minimum for a goat is
60. |
We repeated
the antihistamine, Banamine, and Nuflor on Monday
– along with all her other items. |
Melissa continued
to go out into the field during the day to graze/browse
(although at this time of year there isn't much of
either in Tennessee). She no longer seemed to be walking
on egg shells and was getting around pretty good.
|
Tuesday evening
she had a 12 inch string of mucus; we were concerned
that birth was imminent and carried our stash of old,
but clean, towels to the barn to be ready. We were
still very concerned because she was still 13 days
away from her due date. |
Wednesday
Melissa went out with the herd as normal, but she
no longer could keep up with them and had a hard time
getting back to the barn. She was going downhill fast,
and we were at a loss as to what else we could do
for her. |
So, the vet
was summoned again. He suggested we start her on an
IV and induce labor if we wanted to save Melissa.
He arrived at 8 p.m.; Melissa was already in labor
without being induced. But she was so weak by this
time, she could not push to move the babies into the
birth canal. By 9 p.m. Wyatt was able to deliver triplets
– 2 girls and 1 boy. Unfortunately all three
were born dead. |
|
He started
the IV (lactate ringers, 1000 mL) at 9 with a fairly
fast drip. He also gave her an antibiotic and a shot
for pain. She never flinched. Under his direction,
we hooked up a heat lamp because he felt she would
be chilled (temperature was well below freezing by
this time). Just for good measure, we covered her
with an old Army blanket to try to help her retain
some warmth. When the first bag was empty, we started
a second bag with a slower drip. Afraid she would
pull the IV loose, we stayed in the creeper with her
until well after midnight when the second bag was
empty. |
Melissa died
between 5 and 6 a.m. |
Apparently
we are slow learners. Approximately 3 weeks later
we noticed another doe walking gingerly and laying
around a lot. Quartz, too, was about 3 weeks from
kidding and had her pre-kidding shots. Quartz, though,
wasn't a large doe. In fact, she was one of our smaller
South African fullbloods with a condition code of
5 (on a 9-point scale). Her first kidding had produced
relatively small (5 and 6 pounds) kids while her second
kidding produced a single, healthy girl born 10 days
early. Quartz was still eating well, drinking well,
and was still going out to graze/browse with the other
goats. |
But with Melissa
still heavily on our minds, we tested Quartz with
the Ketone Strips. And we were totally shocked when
we learned she had extreme ketosis! Treatment began
immediately. |
15 days before
her due date, Quartz, whose ketone levels had returned
to normal, died. She was carrying quads – 3
girls and 1 boy. 32 pounds of kids in her relatively
small body. Quartz definitely disproved the theory
that ketosis is restricted to overweight or poorly
fed goats. |
Still we didn't
learn. Approximately a month before Beauty was due
to kid, she started laying around a lot. Now, it was
100 degrees, and a lot of the goats were laying around
a lot – bred and not bred – so we weren't
too concerned. Finally Beauty, one of our less tame
goats, was slow enough for us to catch. A quick check
of her eyes indicated she needed to be wormed, so
we did that before going out of town for a show. Beauty
had not lost any conditioning, so we decided her only
problem was a heavy parasite load. We were wrong. |
When we returned
from 2 days away from the farm, Beauty was down. We
thought it was anemia, so we treated her aggressively
with Magic, iron shots, and vitamins. Since she had
not lost conditioning, had not stopped eating, and
since she was not overweight, it didn't occur to us
to test her for ketones – until it was too late
to help her. Beauty, in her first pregnancy, was carrying
twins. She died 15 days before her due date. |
|
The moral
of this little story: Ketosis must be recognized early
and treated aggressively from the beginning. |
Losing four
outstanding does to ketosis forced us to do research
on the disease and change our management practices
with pregnant does. |
The first
step we took was to purchase an ultrasound machine
so we will know how many fetuses a doe is supporting. |
Ketosis/pregnancy
toxemia is more prevalent in large does carrying multiple
fetuses. |
But, while
it is more prevalent, multiple fetuses are not a definite
"sign." The only way to know for sure if
a doe has ketosis is to test with Ketone strips -
readily available at the local drug store. |
Ketosis/pregnancy
toxemia seems most likely to occur in the last 3,
4, 5, or 6 weeks of pregnancy (depending on which
article you read). According to one source, before
a doe kids it is pregnancy toxemia but after she kids
it is ketosis. |
The second
step we took was to change feed during the later stages
of pregnancy. After the first 45 days of the pregnancy,
we have switched the bred does from 18% protein in
the Co-Op Goat Starter to a 14% protein Farm
and Ranch 14 Pellet for beef cattle on pasture,
maintenance of mature horses, and finishing goats.
In our research we learned goats need less protein
and more starch (energy) in the latter stages of pregnancy.
This did not seem to work, so we found Feed
in a Drum, which is a molassas-based mineral/protein
supplement. The does love. Since we added the supplement,
five does kidded with triplets with no sign of ketosis.
|
Ketosis/pregnancy
toxemia is better prevented than treated. Note: we
did not say easier to prevent than treat. It has been
suggested to prevent toxemia you should not have fat
does during early pregnancy and increase the caloric
intake in late pregnancy by providing a feed high
in energy – all the while eliminating stress
on the doe. That sounds so easy, but we have does
who gain weight by smelling feed. And increasing the
caloric intake is difficult when the doe quits eating
due to lack of space around her rumen. |
The third
step we have not had to take yet. We have vowed though,
that in the future, if we have a goat with ketosis,
we will immediately induce labor and abort the pregnancy.
If the doe can be saved, she can have more kids. If
the doe is within two weeks of delivery, we will induce
labor by giving 20-25 mg. dexemethasone;and labor
should begin within 48 hours. (The dexamethasone,
according to Dr. Laird Laurence, will increase the
survival chance of a kid.) |
Ketosis is
a condition characterized by an abnormally elevated
concentration of ketones in the body tissues and fluids.
(Ketones are acetoacetic acid and beta-hydroxybutyric
acid.) It is a complication of starvation. (Dorland,
27th ed) The babies take up so much room in the doe's
body there is no room for the rumen to function properly.
The doe's body, due to lack of food (starvation) starts
breaking down stored fat (and with most goats there
is very little fat stored) to convert to sugar. |
During late
pregnancy, the level of nutrients required by the
doe are high – as high as during lactation.
But the developing fetuses crowd the abdominal cavity,
reducing volume used by the rumen. According to J.
M. Luginbuhl and M. H. Poore,
http://www.cals.ncsu.edu/an_sci/extension/animal/meatgoat/MGNutr.htm,
"When forage or browse is low in quality, (40%
to 55% TDN; 10% protein or less), does in late pregnancy
and early lactation should be provided with about
1 lb/day of a 16% protein concentrate." According
to the 8th Edition of Merck Veterinary Manual Goat
Medicine, does carrying twins have a 180% higher energy
requirement (carbohydrates) than those with a single
fetus while those bearing triplets have a 240% greater
energy requirement. Fat is metabolized into glucose
when demand exceeds supply. |
The following
are signs (in no particular order) to look for when
diagnosing ketosis: |
|
1. She may have swelling (edema)
of the ankles and lower legs.
2. The doe will lie down a lot; she will become
sluggish and slow to get up.
3. The doe will appear depressed.
4. She will have a loss of appetite – eating
less and less until she stops eating altogether.
5. Her eyes may appear dull.
6. She may appear stiff.
7. She may walk with a limp.
8. Teeth grinding is common.
9. She may have muscle tremors or seizures.
10. Her breath will have a sweet odor.
|
Later signs,
once the lack of glucose has compromised the neurological
system: |
|
1. Blindness
2. Stargazing.
3. Tremors.
4. Ataxia.
|
Finally the
doe will become comatose. According to our vet, around
this time the doe's system will kill the fetuses. |
The first
time you notice a decreased appetite or unwillingness
to follow the herd, action must be taken. Exercise
should be forced. One source suggested putting the
feed and water on opposite sides of the paddock so
the doe would have to walk to either; that didn't
work for us as our does either quit eating or quit
drinking water. Carbohydrates should be increased
by offering whole corn, fresh alfalfa, or soybean
meal. |
Basically
you have to recognize the symptoms then (1) hydrate
the doe and (2) get enough glucose (sugar) to the
brain to wake the doe up. |
Research tends
to indicate an increase in toxemia during drought
or extremely rainy conditions. Please note: the drought
may have been the summer before causing hay to be
lacking in proper, expected nutrition. Extremely rainy
conditions often cause an increase in worm loads which
cause the doe to lose enough body condition to become
a candidate for toxemia. |
While doing
research for this article, we learned there is a lot
of poor information on the internet – some out-and-out
incorrect. For example, according to http://www.goatsprefer.com/
"An adequate nutritional level throughout the
pregnancy will prevent pregnancy toxemia. Excessive
fat should be avoided." Based on our personal
experiences, excessive fat animals are no more or
less likely to become ketonic than skinny animals.
This site also stated, "The disease usually appears
in the last 30 days of pregnancy and is more common
after the first pregnancy." Since exactly half
of our animals who died of ketosis were in their first
pregnancy, I question the source of their statistics.
(Admittedly, 4 is a very small sample size to base
any conclusion on.) |
